Hi,

So sorry if I make you confused. Please refer to the attachments. That's what I'm talking about. What's the name of that part ?

[thechuckster]

are you sure that's attached to the turbo? it looks like a TVIS actuator.

does it move if you supply it with vacuum?


fwiw:- the stock 185 actuator has two ports on it (one connects to the compressor housing, the other goes around to under the intake manifold and connects to a VSV (vacuum switched valve) that part of the factory boost control system.

Ok thanks a lot for the tips.

May I know if I want to replace this TVIS, from what other engine series does this thing share the same part ? Kindly advice. thanks.

3SGE of same era would have similar actuator. Maybe one form a 1GGTE but the pushrod might be different length and mountings might also differ,
